I have tried a lot of stuff to help with rubs. Mustard. Oil. Butter etc. but my favorite esp with hog is a head of minced garlic. I mix the garlic with the rub and really rub it in. Cover well and sit overnight. Then smoke away. Let. Me know if you try it and what you think. Have not done with poultry but will use a bunch of garlic when I do my first brine this year.
